title: "lastSegY"
|
||
excerpt: "Extract the 'y' axis value of the last line segment in the provided 2-d"
|
||
layout: manual
|
||
---
|
||
|
||
Extract the 'y' axis value of the last line segment in the provided 2-d
|
||
|
||
sketch.
|
||
|
||
```js
|
||
lastSegY(sketch_group: SketchGroup) -> number
|
||
```
|
||
|
||
### Examples
|
||
|
||
```js
|
||
const exampleSketch = startSketchOn("XZ")
|
||
|> startProfileAt([0, 0], %)
|
||
|> line([5, 0], %)
|
||
|> line([20, 5], %)
|
||
|> line([0, lastSegY(%)], %)
|
||
|> line([-15, 0], %)
|
||
|> close(%)
|
||
|
||
const example = extrude(5, exampleSketch)
|
||
```
|
||
|
||
|
